  • Process for continuously casting thin slabs
    Patent number: 5871040
    Abstract: In producing thin slabs by continuous casting, a method is developed in which internal defects are reduced to improve a production yield. Narrow sides of cast slabs are cooled in a controlled manner to produce cast slabs having a projection in a center of each of the narrow sides to a height of 5-10 mm above the level of the edge portions, and squeeze reduction with a reduction of 10-45% is carried out while an unsolidified portion of the narrow sides of the slab is within 50-80% of the thickness of the cast slab.
